Answer:

To cross petunia plants/lines with pink flowers (F1) which were obtained by crossing plants with red and white flowers (parental generation). The presence of petunia plants with red or white flowers in F2 would evidence that this trait is under incomplete dominance.

Explanation:

Incomplete dominance is a type of relationship in which both alleles are expressed in heterozygous individuals, thereby resulting in a new phenotype. This type of allelic interaction is commonly referred to as 'the dilution of the dominant allele' in heterozygous individuals. Moreover, codominance refers to a type of allele relationship in which both alleles are expressed to an equal degree in heterozygous individuals.

ndividuals III-6 and III-7 have two little monstersand are expecting a third one. Their two childrenhave two eyes. What is the c

CaHeK987 [17]

Answer:

The correct answer is - 75% or 3/4.

Explanation:

In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.

then chances of single eye offspring would be -

cross: Aa and Aa

gametes: A, a and A, a

Punnett square:

A a

A AA Aa

a Aa aa

so there are 75% chances to have a single eye and 25% chances for a double eye.

During an oceanic plate convergence, the plate, will sink

diamong [38]

Answer:

Actually, when two oceanic plates collide, the plate that is older, therefore colder and denser, is the one that will sink. In a contest between a dense oceanic plate and a less dense, buoyant continental plate, you know that it's the dense oceanic plate that sinks.
